A couple from Lewis Hyde, The Gift:

"Academic freedom," as the term is used in the debate over commercial science, refers to the freedom of ideas, not to the freedom of individuals.

Ideas do not circulate freely when they are treated as commodities.

When all property is privatized, faith is privatized and all men feel fear at the boundary of the self.

Bondage to our gifts (and to the teachers who wake them) diminishes as we become empowered to pass them along.
